Arabidopsis Phytochrome D Is Involved in Red Light-Induced Negative Gravitropism of Hypocotyles

open access: yesJournal of Integrative Agriculture, 2014
The phytochrome gene family, which is in Arabidopsis thaliana, consists of phytochromes A-E (phyA to phyE), regulates plant responses to ambient light environments.

A gravitropic stimulus alters the distribution of EHB1, a negative effector of root gravitropism in Arabidopsis

open access: yesPlant Direct, 2020
In Arabidopsis gravitropism is affected by two antagonistically interacting proteins, AGD12 (ADP‐RIBOSYLATION FACTOR GTPase‐ACTIVATING PROTEIN) and EHB1 (ENHANCED BENDING 1). While AGD12 enhances gravitropic bending, EHB1 functions as a negative element.

A Conditional Mutation in SCD1 Reveals Linkage Between PIN Protein Trafficking, Auxin Transport, Gravitropism, and Lateral Root Initiation

open access: yesFrontiers in Plant Science, 2020
Auxin is transported in plants with distinct polarity, defined by transport proteins of the PIN-formed (PIN) family. Components of the complex trafficking machinery responsible for polar PIN protein localization have been identified by genetic approaches,

PID/WAG-mediated phosphorylation of the Arabidopsis PIN3 auxin transporter mediates polarity switches during gravitropism [PDF]

open access: yes, 2018
Intercellular distribution of the plant hormone auxin largely depends on the polar subcellular distribution of the plasma membrane PIN-FORMED (PIN) auxin transporters. PIN polarity switches in response to different developmental and environmental signals

Advancing vegetation monitoring with virtual laser scanning of dynamic scenes (VLS‐4D): Opportunities, implementations and future perspectives

open access: yesMethods in Ecology and Evolution, Volume 17, Issue 1, Page 33-51, January 2026.
Abstract Virtual laser scanning (VLS) is an established and valuable research tool in forestry and ecology, widely used to simulate labelled light detection and ranging (LiDAR) point cloud data for sensitivity analysis, model training for machine learning (ML) and method testing.

Stem gravitropism and tension wood formation in three tropical woody species with different wood densities

open access: yesJournal of Wood Science
Angiosperm trees develop tension wood on the upper side of leaning stems to reorient the direction of stems towards their normal positions in response to a gravitational stimulus. The development of gelatinous fibers with thick inner gelatinous layers (G-

Circumnutation in the growth of Chara rhizoids

open access: yesActa Societatis Botanicorum Poloniae, 2014
Chara rhizoids, cylindrical cells growing in their apex, having the capability of positive orthogravitropic response, while growing without any change of position are not ideally straight, but they are characterised by slight and repeating cyclic ...

The Fiber Walk: A Model of Tip-Driven Growth with Lateral Expansion [PDF]

open access: yes, 2013
Tip-driven growth processes underlie the development of many plants. To date, tip-driven growth processes have been modelled as an elongating path or series of segments without taking into account lateral expansion during elongation.

Auxin‐mediated statolith production for root gravitropism [PDF]

open access: yesNew Phytologist, 2019
Summary Root gravitropism is one of the most important processes allowing plant adaptation to the land environment. Auxin plays a central role in mediating root gravitropism, but how auxin contributes to gravitational perception and the subsequent response are still unclear. Here, we showed that the local auxin maximum/gradient within the root apex,

Polar‐localized EXO70G1 regulates root development in Arabidopsis thaliana

open access: yesJournal of Integrative Plant Biology, Volume 68, Issue 1, Page 96-112, January 2026.
The putative exocyst subunit EXO70G1 exhibits apical‐basal polarity in Arabidopsis root cells; this polarity stabilizes membrane domains to facilitate targeting of the auxin transporter PIN‐FORMED2 during root development. ABSTRACT Cellular asymmetry, which represents a fundamental characteristic of cell polarity, is prominently illustrated by the ...
